  "table_description": "This table contains metadata about the slide microscopy (SM) series available in IDC. Each row corresponds to an instance from a DICOM Slide Microscopy series available from IDC, identified by `SOPInstanceUID`, and contains attributes specific to SM series, such as the pixel spacing at the maximum resolution layer, the power of the objective lens used to digitize the slide, and the anatomic location from where the imaged specimen was collected. This table can be joined with the main index table and/or with `sm_index` using the `SeriesInstanceUID` column.",
